Negotiation does not end when you accept a job. In fact, many of the highest-leverage conversations happen internally, when you ask for a raise, a promotion, or a change in scope. The principles are the same as external negotiation: prepare with data, know your target and walk-away, frame the ask in terms of impact, and stay collaborative. For a performance review or raise conversation, open by summarizing your key achievements: "Over the last year I've contributed by [list]. I'd like to discuss how my compensation can better reflect my current impact and responsibilities." Quantified, results-focused achievements that are clearly relevant to the role are far more persuasive than general statements about working hard.
Preparation makes a critical difference. Gather evidence of your achievements, understand internal pay bands if possible, know your target number, and schedule a dedicated meeting rather than surprising your manager. Timing matters too: raises and promotions are often tied to budget cycles and review periods, so asking at the right moment improves your odds. Translate your tasks into business outcomes: show how your work improved revenue, reduced costs, mitigated risk, improved customer satisfaction, or enabled strategic goals. A reasonable internal raise in a strong case is often in the 5–15% range, depending on market misalignment, increased responsibilities, and company norms; larger jumps usually require a promotion or role change.
When your manager agrees you deserve more but says their hands are tied, ask what specific constraints exist, what timeline or process could change things, and whether they will advocate on your behalf. A useful follow-up is, "What would need to be true for a raise to be approved, and how can we work together toward that?" If you hear "there's no budget right now," ask about timing and alternatives such as title, scope, or a bonus. When you do get a "not now," summarize the agreed goals and timeline in writing, then revisit at the agreed date with evidence that you have met or exceeded them. If you are using an external offer as leverage, be prepared to actually accept it if the company cannot match, because using leverage you are not willing to act on damages trust. Be cautious about accepting a big internal counteroffer just to stay: research shows many people leave within a year anyway, and underlying issues often remain. And if you do decide to leave, thank your manager, explain your decision respectfully, and offer a thoughtful transition to protect the relationship.
